文摘

A cooperative control of battery energy storage (BES) systems is proposed. The proposed control strategy comprises two control subsystems, for charge and discharge operation of the BES. Employing the proposed method in both charge and discharge mode aims to maintain the power balance of the microgrid (MG), while respecting the SoC level and power rating of the BESs. Moreover, a new virtual impedance strategy is introduced in order to enhance the reactive power sharing accuracy among the BES units and the renewable energy sources (RESs) in the MG. The system performance is validated through extensive simulations carried out in PSCAD/EMTDC software.
